Hi, Mr. Purse Snatcher?

Last night at the Notre Dame basketball game, someone snatched my mom's purse by sneaking under the bleacher and pulling it through. (I was home sick). When we start to cancel all the credit cards and stuff that was in it. I decide (I think because I saw in on Seinfeld once) to call her cell phone. As it's dialing though, I suddenly panic because I have no idea what I would say if the person answered (he does have our adress afterall). He didn't. It went to voicemail.
